The investigators are still in search of cockpit voice recorder which is unrecovered so far.
So not found yet. Seen where the accident site is located , a money reward would probably speed up the recovery .
Sorry for off topic : on the BEA old video posted ( thanks for that one
krismiller ) the FE calls "V2 plus" . For those here old enough to remember , was that an early 707 procedure of another local BOAC addition ? never heard this before ..
